example 1

[0419] Make a query to check if the address below exists in the database.

[0420] "12 / 34 Pitt Street, NSW, Sydney"

[0421] By generating a text object on this input and establishing low-level matching properties:

[0422] "12"

[0423] "34"

[0424] "Pete"

[0425] "street"

[0426] "Sydney"

[0427] "NSW"

[0428] Analysis of the intersection of all index entries retrieved using the above attribute type identifiers and values ​​will produce the records at the beginning of this section.

example 2

[0430] Make a query to find all addresses that contain a street:

[0431] "Pitt Street"

[0432] Create a text object on this input and generate an index key set:

[0433] "Pete"

[0434] "street"

[0435] Here, analysis of the intersection of all index entries retrieved using the attribute type identifiers and values ​​described above will yield the correct secondary group of records, including the record at the beginning of this section.

[0436] The above example is very simple, the purpose is to demonstrate the concept. In the actual system, once the low-level matching key set is generated, all the techniques in the "keyword search" can be used for each attribute type sub-set. For details on the "Keyword Search" technique, see the book and magazine article by Gerald Salton.

Abstract

A method and apparatus for processing free-format data (301) to produce a "text object" associated with the free-format data. The text object comprises a plurality of "component nodes" (302-312) containing attribute-type identifiers for elements of the free-format text and other data facilitating access to the text object to obtain information and / or change or add the free-format data. This arrangement obviates the need for the provision of separate database fields for each element of the information. Free-format data can therefore be processed in a similar manner to the way a human being processes free-format data. All elements can be accessed via the constructed text object.

Description

[0001] The present invention relates generally to the processing, storage and analysis of information in the form of free-form data, and in particular, but not exclusively, to methods and apparatus for interpreting free-form text. Background of the invention [0002] One of the main purposes of a computer system is to manage information. This information management is realized through the data management system inside the computer. [0003] In general, data management systems can be divided into two categories: 1) database management systems; and 2) text search and retrieval systems. [0004] The first type of data management system stores data in a specific format inside the computer so that the data can be preserved and further edited. When required, these systems will represent the data in a specific format for humans to read the data or for other systems to use the data. Data management systems in this category include: hierarchical, network, relational, object database ...
